Why is using the open array parameter illegal using the Object type?
========================

{$mode objfpc}

program test;

type
   TMyObject = object
     constructor Create(text: array of String);
   end;

constructor TMyObject.Create(text: array of String);
begin
end;

begin
   TMyObject.Create(['1', '2', '3']); // error: Illegal expression
end.

Objects are not classes, they don't know the Object Pascal style syntax 
for creating them, instead you need to use the syntax for objects from 
TP times:

=== code begin ===

program tobj;

type
  TMyObject = object
    constructor Create(text: array of String);
    destructor Destroy;
  end;
  PMyObject = ^TMyObject;

constructor TMyObject.Create(text: array of String);
begin
  Writeln(Length(text));
end;

destructor TMyObject.Destroy;
begin

end;

var
  o: PMyObject;
begin
  New(o, Create(['1', '2', '3']));
  Dispose(o, Destroy);
end.

=== code end ===

Regards,
Sven
